For waterproofing a concrete swimming pool, we proceed as follows:
Step 1:
Clean all surfaces from petroleum-based materials.
Step 2:
If surface or deep cracks exist on pool walls or floor, open and clean the cracks in a V-shaped manner.
Step 3:
Using adhesive and N50 concrete additive with 25% waterproofing and 75% strength enhancement properties, repair cracks to achieve a uniform surface.
Step 4:
Perform chamfering using N50 concrete additive and adhesive.
Stage 5:
For the final layer isolation, we use a waterproofing adhesive and Z90 resin that has 100% waterproofing properties. The waterproofing adhesive and Z90 resin have a three-stage implementation method known as the 222 formula (this method includes 3 stages, with each stage being performed twice).
- Stage One: Mix one unit of waterproofing adhesive and Z90 resin with one unit of water, and apply using a brush or spray gun.
- Stage Two: In one container, mix one unit of waterproofing adhesive and Z90 resin with one unit of water. In another container, separately combine one unit of cement and two units of sieved stone powder (Silica SI30), ensuring the resulting slurry is brush-applicable.
- Stage Three: Repeat Stage One (one unit of waterproofing adhesive and Z90 resin + one unit of water)
Notice:
If you want the final work surface to have color, add 3 base water units of paint to the third stage (1 unit of Z90 resin sealing adhesive + 1 unit of water + 3 units of acrylic paint)
